Thanks, daal. I'm enjoying them as well, even though I've lost a few.

What if he plays P1 in response to P2?

Yes, I was surprised, too.

The gap at prevents White for cutting you off. Black connects at "a" next and reduces the center at the same time. Black is still in the game. If White "a" instead of 10, Black plays atari at "b", White has to capture at "c" and Black connects at 10, capturing White's center stones.

I just had time to look at this sequence more in depth, and it's pretty beautiful. Thanks again for sharing.

You lost almost a whole move by playing E14 instead of E17!

Of course he'll answer, that's hardly the point. E14 first is a huge mistake.
Joseki is E17 first, since if you play E17 first your opponent has to avoid dying and play B13, after which you'll still get E14. But much more importantly: you'll get sente. (If you exchange E14 first you'll end in gote, which is a serious problem.)

Theoretically white could also D13 instead of B13 to deny E14 to black, but that leaves worse aji on the side.

Either way, the important thing to note is that you were supposed to get sente here.

edit: guess yoyoma beat me to it :P

I didn't post a detailed explanation because I was curious to see how Kirby would respond.

Kirby, I saw other posts where you ask pros for advice on how to improve. They said play quick games, and you are playing those quick games. But in the comments I see "I've heard this isn't right, but I don't see why". Did you look at a joseki book? Eidogo shows this joseki and explains why you lost a move.

Thanks, yoyoma and leichtloeslich. That's awesome. I never knew that it was because of the difference between sente and gote. That's really fascinating, and now I know the reason for that order. I felt that I heard that the other move was right, but I didn't realize this sente/gote fact, so I couldn't make myself play it.

So standing at F5 in the game is the standard play and there is no example from pro play of the "honte" at E5. Punishing this baby may be more difficult than we expect!

Interesting, ez4u. I thought solidly capturing would be superior, since I could get the forcing move in. I think my forcing move was sloppy, though, don't you?

Kirby · Post by **Kirby** » Thu Jun 13, 2013 11:04 pm

By the way, are there examples with white influence along the left side? I feel this is relevant in the current situation.

P.S. You are my role model, ez4u.

My impression was that D6 or D10 were too early, and that black could have kept the game even by just playing calmly on the right or top sides. Just a sanrensei or something like leaves black developing on a much larger scale than white.

Flattery will get you everywhere!

Let's step back to the beginning with our database...

In 437 games from the position below, Black played

265 times (the low approach at 2 was the choice 112 times). Basically Black does not want to play san-ren-sei and let White blunt the formation with a shimari at 2 or some other play on the bottom. (Note however, that the 16 times in GoGoD that Black went ahead and played 1 at Q10, the results are about even so as always YMMV)

About 70% of the time White goes ahead and attaches underneath at

. In return Black almost always plays the hane at

. This is natural since Black's potential framework from the upper right wrapping around the lower right to the lower left is bigger than White's framework on the left side (this is important!!!).

In the 182 games where White pulls back at

, we see that Black connects at

145 times, plays the hanging connection at "a" 27 times, jumps into the center at "b" (invented by Takemiya of course) 7 times, plays on the right at "c" twice, and plays in the upper left (at "d") a grand total of once. Now repeat after me, "This is natural since Black's potential framework from the upper right wrapping around the lower right to the lower left is bigger than White's framework on the left side (this is important!!!)."

Currently I think you way over-value sente. Note that in this game, as in nearly every game,

,

, and

below were ALL gote. What were you knitwits tinking? How could you make four gote moves in a row? Weren't you worried about that!

Actually the database shows that

is pretty much sente. However, in order to ensure that, White has to play a low move relative to the left and entice Black into playing a move that is overall favorable - to Black. So the price of keeping sente may be higher than White should have been willing to pay.

Remember that in the opening there are always other big moves to be played. If there weren't, it would no longer be the opening.

By and large, if Black focuses on building his own frameworks, White is going to have to enter sooner or later and fight there. The komi allows White to settle for less from such a fight than if there were no komi but that is the nature of Go. If on the other hand, Black focuses on erasing White's potential rather than building his own, then Black commits to fighting within White's area of influence. It is not impossible to play that way, but to some extent Black is voluntarily giving up the advantage of the first move. At least Black is running the risk of ending in gote(!) and letting White seize the initiative.

Have you watched Bat's lectures on youtube? I watched a bunch of the games and enjoyed them. One thing that struck me about his play compared to mine (yep, I am more like you than I am like him

), he often is content to just continue developing his own framework rather than immediately challenging his opponent. I think this is a good, calm approach to cultivate. If we can't afford to do so, we have to immediately ask where did we go wrong in the moves up until now. Since the game starts out balanced, it should not be urgent that we forcefully interrupt our opponent's early play unless we have already made a mistake somewhere. In that case the question is not what to play next but rather what to fix in the next game.
